I need to convert a LVDS clock into a single-ended signal. In the past I've used a voltage balun with a center tap on the secondary but I haven't found any good past 1GHz. I need to get to 2GHz in this application and found transmission line baluns good from 4.5-3000 MHz like the TC-1-13M+ from Mini-Circuits.

Analog Devices should an implementation of it on an eval board schematic in their datasheet for the ADL5391 (page 13). It looks like R4 is the matching for the output impedance of the IC but what is unclear is why they added R5/R6. Is this to present a 150 ohm differential impedance (R4+R5+R6) to the balun? The balun is 1:1 so doesn't that mean the single-ended output impedance is 150 ohm? The datasheet mentions the balun is 50 ohm. I feel like I'm missing something here.

I'd appreciate any clarification you can offer.
